Concept:These processes are explained by the fact that matter is made up of tiny particles in constant motion.Explanation:Evaporation: particles escape from the liquid surface, showing particles are in motion.Sublimation: particles change directly from solid to gas, indicating particle rearrangement.Diffusion: particles spread out and mix with other particles.Brownian motion: visible particles are knocked about by invisible particles of matter.Answer:D. I, II, III and IV
